Hello guys! It has been some time since I made a topic on this forum so I thought I should make another, I am going to list all the cheats in GTA IV for both the Xbox 360 and PS3.
Cheats in GTA IV may be activated via the ingame cell phone by calling the numbers listed here.

These cheats the official cheats (and confirmed) for the PS3, Xbox 360 ans PC versions of GTA:IV, I hope this helps you if you do not already know the cheats to this game.
Also members may contribute by posting any new cheat codes as/if they become available.

Considering all the cheats are entered via mobile phone, it could be a lot harder to do that. Assuming all the numbers are XXX-555-XXXX, that allows for 10 million possible combinations Not to mention the button presses to enter the cheats are a lot more complicated.

...No, I'm not very creative when it comes to this sort of thing.

Calm down people please?
Give it a bit more time! More cheats will eventuraly become available for GTA Iv and when they do you guys can post them in this thread and I will update the list.
I also check several gaming websites on a daily basis so when a new cheat/s come/s out I will update this topic!
Thanks.
